v UNITED STATES Be it known that I, HENRY A. BIERMANN,

"citizen of the United States, residing at New Orleans, in the parish ofOrle'ansand State of Louisiana, have invented new and useful Improvements in Heating Apparatus, of

' which thefollowing isa specification.

My invention pertains to I that type of heating'apparatus inwhich an open-grate fire is utilized .tolieat airincidental to'the passage of the air fromtheatmosphere into an apartment; and it consists in the peculiar and advantageous apparatus hereinafter described and particularly pointed out the claim appended;

In the drawings, accompanying and forming. part of this specification: Flgure-l is a view, partly in elevation'and partly in secnon, shownigan apparatus'constructed 111- accordance with my inventio'n'and arranged to condu t heated air into the apartment which ad oins that in wh ch the open-grate fire is arranged. Fig. 2 is a view similar to:

a Fig. 1, biit illustrating a form of apparatus 1 thereof:

arranged to conduct the heated air into. the same apartment in which the open-grate fire 1s arranged. Fig. 3 is an enlarged horizontal section taken through the several vertical pipes of my apparatus in a plane slightly above the lower header thereof. Fig. 4. is a detail vertical section, taken in the plane in? dicated by the line 4-4 of Fig. 3 and illustrat-ing import-ant constructional details of the apparatus, hereinafter set forth in full.-

Referring by letter to the saiddrawings, and more particularly to Figs-1, and 4',

which the smoke and other products of combustion are conducted away from the fire-,

place.

In carrying my invention into eif ect, I

provide the apparatus illustrated in Figs. 1,

3 and 4, arranged as shown in Fig. 1, rela'-,

tive tothe fireplace A, the wall B and the chimney C. The said apparatus is made up of a lower header b, preferably of cast-iron,

an upper header 0, preferably of the same material as the lower header, a conduit 03, designed to lead from the atmosphere or any 1 othersuitable fresh-air supply and conduct PATET orr oa HENRY A. BiERMANN, or. ORLEANS, LoUIsIAria H imA-Tme' APPARATUS. I

It will also be noted that in the arrangement' shown in Fig. 2 the fresh-air supply pipe 01, leads to the middle of the bottom of the lower header 2). v

' In both embodiments of the invention, the lower and upper headers are connected, and the upright pipes are'arranged, relative to said headers, in the same manner, and for this reason a detailed description of ,the lowerand upper headers, the vertical pipes, and the connections, shown in Figs. 3 and 4, will sufiice'to impart a definite understanding of the said parts irrespective of the embodiment in which the same are incorporated. As shown best in Fig. 4, the lower and upper headers are provided in their adjacent walls with vertically disposed apertures g with which communicate countersinks h. In these countersinks and against the inner walls thereof the ends of the vertical pipes e are arranged and sealed by cement 2', of fire resisting nature. Extending downwardly through the upper header, the two end pipes e and into the lower header are two vertical rods D, each of which is threaded at its upper end to receive a nut is, and is provided at its lower end with a hook j which embraces the portion of the lower header between two of the apertures 9. By virtue of this construction it will be manifest. that when the nuts 7c are tightened, the lower and upper headers will be drawn tight against the lower and upper ends of the pipes also, that the lower and upper headers are strongly connected together, and this in such mannerthat when desired the lower and upper headers and the interposed pipes may be expeditiously and easilydisassembled for purposes of repair or for other purposes. It will further be noticed in this connection that the connecting rods D are contained in the lower and upper headers and end pipes e and in tne presence of the fresh air and isolated from the tire and the highly heated products of combustion, From this'it follows that the efliciency of the rods D will not be affected by the fire or the heat, and hence the said rods will last and will strongly connect the headers for an indefinite period. The location of the nuts l'e above the upper header 0 makes said nuts readily accessible, and when said nuts are removed it follows from the construction described that the parts may be quickly .and easily disassembled.

It will be gathered from the foregoing that the fresh air in both embodiments of my invention enters the middle of the lower header and is distributed among the several upright pipes by which it is discharged into the upper header, and that from said upper header the heated fresh air is supplied to the discharge pipe or conduit leading from the middle of the upper header. This is p 'actically advantageous inasmuch as it as sures all the fresh air being uniformly heated precedent to the discharge of the same into the apartment to be maintained in a heated state.

Having described my invention, what I claim and desire to secure by Letters-Patent, is: v

In an apparatus for the purpose described, the combination of headers having sets of alined apertures in their adjacent walls and also having countersinks formed in the adjacent sides of said walls and colnn'mnicating with the apertures. pipes extending between the headers and having their ends arranged in the said counters-inks and against the inner walls of the counters-inks, cement seals arranged in the countersinks and about the ends of the pipes, connecting rods extending through the upper header and the end pipes of the set and each having a hook at one end embracing the portion of the lower header that is between two pipes and also having a threaded portion extending above the upper header, and nuts mounted on said threaded portions of the rods.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
